* Use breakpad_getcontext on all Linux platforms missing getcontextMichael Forney2020-03-169-25/+54
| | | | | | | | | | | | | | | | | | | | getcontext is also not available on musl libc, so generalize breakpad_getcontext so it can be used as a fallback for non-Android platforms as well. On x86_64 and i386, ucontext_t uses an Android-specific offset for storage of FP registers, since its sigset_t differs in size. So, make the definition of MCONTEXT_FPREGS_MEM and UCONTEXT_FPREGS_MEM_OFFSET conditional on whether we are building for Android. On glibc and musl, signal.h and asm/sigcontext.h can't be included together, so in breakpad_context_unittest.cc, only compare the libc and kernel _fpstate when on Android.

| | | | | | | | | | | | | | | The _libc_fpstate struct tag is an implementation detail of glibc, and musl uses a different struct tag, _fpstate. Unfortunately, the public type fpregset_t is a pointer type, so is not suitable for allocating storage, or referring to constant storage.

* android: truncate lower of two overlapping modulesJoshua Peraza2020-02-211-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | Previously, the processor truncated the upper of two overlapping module ranges to compensate for incorrect reporting of module ranges by the Breakpad client. Crashpad correctly reports module load ranges, so this truncation strategy is no longer necessary. However, when partitioned libraries are used, the base library may have a range which encompasses the other partitions. When this is combined with the truncate upper merge strategy, the base library's executable segment is truncated causing symbolization failures. This patch changes Android's merge strategy to truncate the lower range (which is still the base library, but this strategy truncates from the high end of the library's range, instead of its base).

* linux, dump_syms: set module name from DT_SONAMEJoshua Peraza2019-10-244-44/+78
| | | | | | | | | | | | | The Breakpad and Crashpad clients will use an object's DT_SONAME as the name for a module if it exists. Previously, linux dump_syms would assume the basename of an input elf file matches that value, causing symbol lookups to fail if they were mismatched. This patch updates dump_syms to use DT_SONAME as the module name, if present.

* Mac dump_syms: accept __DWARF segment without __debug_info sectionMark Mentovai2019-08-072-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | A .dSYM may validly contain a __DWARF segment without any __debug_info section. This can occur for Chromium Framework in a component build of Chromium, because in that case, all of the code is in other libraries that Chromium Framework depends on. This was previously tested by an assertion, but the assertion did not trigger in NDEBUG (release) builds. In NDEBUG builds, this condition would lead to an out-of-bounds read, detected by AddressSanitizer. Instead of an assertion, the check is now always done at runtime. Instead of being fatal, it's now just a warning, because it's been established that __DWARF without __debug_info can occur. (In the Chromium case, it remains pointless to run dump_syms via the "chrome_dump_syms" target on a component build, as it'll only attempt to symbolize Chromium Framework, and not any of the libraries that Chromium Framework depends on that actually contain the code.)

* string_conversion: fix pointer mathMike Frysinger2019-08-053-2/+67
| | | | | | | | | | | | | | | | | | | | | | | Since target_ptr is of type uint16_t* already, we don't need to scale the byte count as the language does that for us. If it were void*, we would need this code, but it's not. In practice it's probably not a big deal due to how we preallocated memory: when converting UTF8->UTF16, we'd reserve the same number of code units, and UTF8 takes more code units per codepoint than UTF16, so the UTF16 vector is always oversized. When converting UTF32->UTF16, we also reserve the same number of code units, but since one UTF32 code unit could require two UTF16 code units (for U+10000 codepoints and higher), we would probably corrupt memory in the process. The APIs in this module don't seem to take into account that range in general, so for now I'm only fixing the memory corruption.

* arm64: strip PACs from link register valuesJoshua Peraza2019-07-232-1/+33
| | | | | | | | | | | | | | | | | | | | | | Pointer authentication codes are used to validate pointers against accidental or malicious modification by storing a hash of the address and a secret value in the pointer's unused, upper bits. The exact bits used may vary by implementation and depend on the size of the virtual address space of the target system, and whether other tagged pointer features are in use. Apple has implemented PACs in the Apple A12. https://developer.apple.com/documentation/security/preparing_your_app_to_work_with_pointer_authentication The documented method of stripping PACs from a pointer is to call ptrauth_strip(), which ultimately emits an `xpaci` instruction, but this option isn't available to the Breakpad processor not running on the device. Instead, this patch selects likely address bits from link register values by examining the address range of loaded modules.
